Dell Vostro 200
Dual video cards including
Intel G33/G31 Express Chipset Family
Nvidia GeForce FX 5500
Two daisy chained Dell projectors (here's the string of components)
CPU > Intel G33/G31 Express Chipset Family > 2 year old Dell 2400mp > 6 month old Dell 2400mp
The second projector is intermittently displaying a resolution incompatible error message. Some of the variables that cause it to come back on include cycling the PowerPoint (run) on and off, cycling the PowerPoint (program) on and off, cycling the projector on and off, cycling the CPU on and off etc... The sequence of turning the projector and the computer on doesn't seem
to matter from my experience. Thoughts on sequence?
One thing that I can reproduce fairly often (not always) is that if I have the PowerPoint not running i.e. only the desktop is displaying and move the mouse over to the offending projector it will start working. If I immediately move the mouse back to the primary desktop and run the presentation it only stays running for one second and then goes back to the error message. If I leave the mouse on the secondary (projector) monitor it will stay and becomes more stable after a few seconds.
We primarily use this setup for PowerPoint.
- Ideas about why the mouse helps the situation?
- Does sequence of turning the three components and running the PowerPoint have any factor?
Hopefully we can work with simple ideas first that I can do without having to pull a ladder out... The projectors are mounted 20 feet up on a ceiling. When I installed, both projectors were working fine and after a few days this problem appeared and has been intermittent ever since. I wish I had more clues as to what causes it to happen. Sometimes it just works when we turn the system on. More than often it doesn't
Any help you can provide would be greatly appreciated.
